There is a tank whichis supported in connection with la. weighing ormeasuring device in such manner as to weigh or measure the contents ofthe tank, andof the quantity i removed therefrom.

In vthe present ex'emplication there isa vsupport 16 which mayv take theform of a pedestal, as shown at 17, mounted ona base 18, which may reston or lbe secured-to the floor. The support may take the form of abracket I9, as shown in Fig. 12, which vbracket may comprise a plate 20ysuitablysecured to a wall or upright exemplifiedV at 21.

.A bowl is shown Von the. support, "and may be a part of the same. Thepedestal, and the bracket it employed, maybe a pipe, which in the formof the pedestal communi- .cates with a trap 26`in the base', froinwhicha. 'waste pipe 27 extends. Vhenthe support is in theform oabracket, thepipe may discharge into -a trap'28, located in the supporting plate 20of the bracket-,and have a waste pipe 29 communicate therewith.:y Theypipe ofthe pedestal Yor bracket. serves as a. Waste The bowl comprisesaweb3l, iii-which there is a T-passage- 32,.and at the outsidefof which,between said web and the outer Wall ofthe bowl, there areoutlet-passages 33. The T-.passageforms an inletI or feed-passagehaving. openingsv 35, 36, yat the outside of the bowl, and an opening 37at the inside offitheb'owl.

Feed-pipes 3S,39,vare connected with the .inlet openings, asfby havingusual threaded connections therewith. Valves 4l, 42," are .located .insaid: pipes for regulating the :in-

fflow of fluid, independently through each of employed for feeding waterof ordinary temperature', as from a., public service" pipe. or fromother suitabie source, and the z other pipe and valve may be,employed'for'feeding heated water or steam. The" valvesregulateandcon'trol or shutoi the supply of iuid of either temperature.Thus the valve il may be employed orwater of ordinaryV temperaturefandthe valve 42 'for the heated water 0r steam. y

A feed-pipe't extends upwardly from the web and'has threadedc'onnectioiiwithfthe port 37 of the inletpassage :inthe support. This feed-pipe`forms a continuation of the support and has a. coupling 4:6 atits-upper One of lconnection with the upper end of the feedpipe. Branchfeed-pipes 48, 49, have connections shown as threaded connections, withthe ports 50, 51, these branch pipes having depending sections 52, v53,extending therefrom, shown closed at their lower ends by caps 54, 55.Preferably one of the sides of each of said depending sections has holes56 therein, extending in directions to cause the jets of liquid ejectedtherefrom into the tank to be injected inthe same directionsA y A lower.fork 85 of said link has articulation about the tank, and preferablydownwardly so as to cause a swirling motion of the body of liquid in thetank to thoroughly mix said liquid. i l,

The coupling at the top of the inlet-pipe vpreferably has an upwardextension 58, vwhich preferably formssupportingmeans for the tank, thelatter being exemplified as surrounding the inlet-pipe, forming acompact construction, and also providing a medran supporting means forthe tank, for providing accuracy in the weighing of the con-- tents ofthe tank.

The ybottom of the tank is provided with a central aperture 61, in whicha pipe 62 is secured to form a liquid-tight joint, as by having threadedconnection 63 with the wall of said aperture, formingl an outlet-spoutfor the tank discharging into the bowlw25. This pipe is shown asextending upwardly into the tank, andy is of the ydesired height for thedesired limit-of capacity'of the tank. The liquid in the tank isarranged to overiiow into this pipe, and to be discharged into the bowl25, through the outlet-passages therein, and the outlet-pipe of thevpedestal or bracket. The height of the outlet-pipein i the tank willdetermine the amount of liquid which the tank may receive prior tooveriow, and thus regulate-the weight or quantity of liquid vwhich thetank is to receive. Any desired less quantity may be received 1n lthetank and. be measured or weighed.

'f TheVV manner of supporting the tank is exemplified as the upwardextension 58, which is in the form o f a fork atrtheupper end of thesupport or standard, and a beam 65. The beam has pivot connection withthe fork, asv by having a knife edge lug 66 at `eachside of thebeamreceived in sockets 67 in the fork. V

A rod'69 extends from one side of the tank in rigid relation therewith.A link 70 connects the adjacent end of the `beam with the rod, this linkbeing preferably fork-shaped at its respective ends, the upper fork 71being received about the beam and connected therewith b v means ofknife-edged lugs 72 received in holes 73 of said fork at the respectivesides ofv said beam, and a pin 74 eX- tending through the lower fork 7 5and recei/ed in a recess 76 in thelower face of theV roe 69.

The rod has a counterbalanceV weightA 77 thereon, which is adjustablelengthwise oi the rod by having a threaded hole therein threaded to thethreaded portion of the rod,

and a clamp-nut 78 received over'saidthread- 7e Y ed portion for fixingthe counterbalance weight in place.v

rihe other end of the beam has a link( 81 articulated therewith, as byhaving an upper fork 82 in which the beam is received, the te beam beingprovided 'with knife-edge lugs l. 83 received in holes 84-of said upperfork.

with one member 86 of a- 'scalesj87, as by means of a pin 88 receivedthrough holes inta saidflower fork and a hole in a shank 89'extendingfromthe member 86 of the scales. The other member 91Aof, the scales Vhasa shank 92 extending therefrom, which is artic- -tends from the .pipe102, and forms partcof'ee theV discharge-pipe.

rlhe contents of the tank, after suitable tempering and mixing andweighing or measuring of the same, may be discharged into the containerwhich is to receiverthe auf same, which may be a mixing vessel` for'mixing a batch of batter or dough or for other purposes. v f v As theliquidl is fed into the tank, orthe liquid is discharged therefrom,Ythe'weight 105 and volume of the liquid .in the tank varies. Thesevariations are shownon the dials 106, j 107, of the scales, whichindicate respectively the weight and volume of the contents. This scalesis shown: as comprising the rela- 1m tively movablemembers 86, 91. Therelative movement isl controlled according to` the .weightcr volume vinthetank, to weigh or measure'` the same, a suitable device beingprovided to indicate such relative movement 115 so as .to indicate such'weight or volume.

The means for controlling the relative movement is exemplifiedgassprings 108, 109, the respective ends of which areconnected with therespective movable members, as by 12e having one of the ends of thesprings received through eyes 111, vfixed to the movable member 86, andhaving the lother ends 'of the springs in the form of hooks 112,revceived through-'holes 113 in the movable 125 member 91. Means areprovided for guidingV relative movement between saidV members, shown asa right line'movement, and as .guiding means comprising a lug 114onmember 86, guided by the walls of a slot 115 on'the 1352 ymember 91,and-a bar 116 on member 91 guided ina guideway 117 in member 86.

y Inthe presentexemplification the dial-106 is divided intopounds, andthe dial 107 is divided into gallons, although other denominations maybe employed. An indicating member comprises a point-er 118 and a pointer119, respectively registering With the respective dials 106, 107. Thepointersare preferably adjustable with relation to each other, as byfixing the pointer 118 to a shaft 121, and adjustably positioning thepointer 119 withvrelation tothe pointer 118, so as toposition'bothpointers to normally register respectively with zero markson the dials 106,107. These two dials are preferably invfixed'relatiomas by having them respectively on plates fixed togetherin suitable Vmanner, and 'having the dial 106xed to the member 86ofLt-he scales.

The pointer-118 may be provided with a .bearing 122 having a square holereceived .thereto in coincidence with Zero on. the

dial 107.

Motion is imparted to thepointers and the shaft on whichthey arelocated-by provid- .iingvzthe shaft witha pinion 131 which .is

meshedby arack 132 on:the:bar,f116 securedv to the member 91. rlheyshaft is journaled in a bearing located in a bracket 134 fixed to themember 86 and in abearing A135 in the dial plates.

In the present exemplification the Arelative movement between themembers ofthe scales is twicethat of the tank,for thereason that vthereare opposite movementsof thetank and that end of the beam with-which thescales has connection, making indications of vminute dierences of weightin the tank possible on the scales.

The bowl 25 is preferablyxprovided with an inlet-passage 138 directeddownwardly into the outlet-pipe and having a baffle-wall 139 of suchform as to direct the overflow liquid from the outlet-pipe 62 past theinletl passage 138. The end of the flexible pipe may be received'in thesaid inlet-passage for discharging rliquid from the tank into theoverflow pipe, incase, for in'stance,-it is desired to emptythe tank, orto reduce the amount of liquid in the tank Without utilizing the same,or to reduce the amount-'of liquid in the tank to .correspond withde--straps and threaded into the bowl.

The lexibledischarge lpipe is employed for discharging liquidffrom thetank intoithe container in .which the liquid is 'to be utilized; =Whennot inuse, the endl. of the flexible pipe may-be received through aring141 secured vto the itank. The flexible pipe is a part of the weightwhich is registeredronfthe .scales and a part ofthe weight which iscounterbalance counterbalanced by the weight 77, Whichlatter-is-regulated;tol cause 'the weight of the tank and: its attendantparts to register zero on the scales.

` yIn the presentv exemplication the;tank.is supported from its upper4end. 'Inorderftof avoid undesirable vibrationof the lowerend ofl thetank, strapsv 143 are provided, articulated respectively with lugs. 1144.depending from the bottom of the tank, at thelouter ends of saidstraps, and with therbowle25 ati thel innerendsof.y said straps,.theiirst'finamed articulations being by means of. screws and nuts .145.passing through holes f in ithegouter .ends of said straps and lugs,the. latterarticulation being by means of screws 1.46l passing throughholes inthefinnerfends of. said n These holes are sufliciently large :orformed vasfslot-s and the `articulations are sufficiently Lloose topermit free weighing or measuring move-f. f -ment ofthe tank, but limitlexcess vibrations thereof. The straps .are shown locatedat'the`respective 'sides ofthe ibowl and extending diagonally `to opposite:sides ofl the tank.

`(See Figs. 25and14.) l y The 'temperature of the contents vof the tankis indicated on a thermometer 15:1,r-the opening 15.4 .in 'thetanlnandthav-ing close connection with Asaid 'tank by fmeansof a gasket 155and a gland 156. The bulbofgthe thermometer is suitably. secured'insa-idrthimble, as by having the indicating bar 1157 thereof threadedinto the .outer endl vof said thimble, this bar having a usual scalethereon.

vbulb-1520i? which is received in agthim'ble 1153 extending throughvandsecuredyingan lll) The thimblegis,preferably of'meta-lfso as toprotect the bulb Aof the thermometer, the metal readily transferring`the heat ofi-the contents of the tanky to the thermometer, yandthe-swirling 4or-mixing motion imparted to said contents by theinjection of the jets of fluid readily mixing said contents so as toimpart eventemperaturethroughout said contents. The colder and hotter:parts yof Vthe fluid 4received through the rrespective inlet-pipesreadily-mix in the feed stand pipe and the branches thereof, so thatbythe-time they are discharged into the tank they'have 'been quite`thoroughly `mixed, the mixture being continuediby the rotating-,ofthe-liquid in the tank by 'the directions in `which the jets areinjected thereunto.`

JThe tank isprovided with acover 1161 having lan annular bead 162-Yreceivedwithin the wall vot thev top of the tank-and shown formed of a.plurality ot sections which sepi aratealong the vmedian joint163,'which includes an opening 164' about the supporting lug 58. vThejoint comprises a flange 165 on oneof the Ysections of the coverarranged to receive the inner margin ofthe other section of the coverbetweenA it and-lugs 166 secured to the section of the cover on whichthe flange is formed. -v

The outlet-pipe is preferably spaced from Vthe feed-pipe by a. space'168, extending .around the feed-pipe, forming an outletpassage betweenthe :feed-pipe and the outletpipe. The tank and the discharge-pipe arearranged to have tree movement with relation .to the 'feed-pipe, andtheoutlet-pipeV may be of such height as to limit the height of contentsofthe tank. The tree lateral movement ot' the discharge pipe about the.eedi e aids .in reservino tree aassaO'e through the discharge pipe andprevents clogging of the discharge passage, and also aids in freedom andextent o'l movement of the hose 104. y

In employing my invention, the valves 4l, 42, aremanipulatedto regulatethe relative proportions oi" colder and hotter liuid to ap proximate thedesired temperature of the liquid in the. tank. The fluid passingthrough said valves passes through the stand feed-pipe andthe branches48, 49,

thereof, being discharged through the holes 56,. the'iholes beingdirected torcause the ro-l tating movement in the tank, the colder andhotter fluids mixing in their passage through the stand pipe and itsbranches, vand while rotating in tlietank. The holes inv the.branch-pipes are related so as to rotate the liquid not only laterallybut in up and down direction to thoroughly and quickly mix the Ventirebody ot' liquid.

=As the amount of. liquid in the tank increases, its weight andquantities are also indicated on the scales 87.V The temperature of thefluid isalso indicated on the thermometer 151. It thethermometerindicates that the liquid in the'tank should be hotter,

. the valves 4l, 42, are manipulated for either decreasing the amountotcolder fluidy or increasing the `amount of hotter fluid, to increasethe temperature of the liquid in the tank, as indicated on thethermometer,'to the desired temperature indication on the thermometer.It the liquid is to be colder, the valve or valves'are reverselyoperated for decreasingthe temperature of the liquid in the tank.V

In this manner the desired `temperature for the liquid which is to bedischarged into the bakers batch may be regulated with accuracy and itsweight or volume may also be regulated with accuracy. It the desiredamount of liquid has been received in the tank, as indicated on thescales, and is. of
